New DNA analysis techniques are helping identify more victims of the attacks on the World Trade Center on Sept. 11, 2001, scientists in the office of New York City's chief medical examiner said Thursday.

Using new technology it pioneered, the medical examiner's office said it was able to recently identify financial worker Scott Michael Johnson, 26, who worked on the 89th floor of the South Tower.
